Thanks again for this and the many contributions you've made to this list and
the field.

There is a lot of noise on this channel, but there is also a lot of amazing
content, including this. Thanks.

> Directions to Explore
>
> 1. What are controlled natural languages (CNLs)?
>
> 2. What are semantic systems?
>
> 3. Common Logic and its mapping to and from CNLs.
>
> 4. CNLs as a bridge between NLs and formal systems.
>
> 5. Methodologies and missed opportunities.
>
> 6. Full natural language, jargon, slang, and folksonomies.
>
> 7. How can semantic systems facilitate the interoperability
> and integration of all systems, independently of the language,
> tools, or methodology with which they were implemented?

> Slide 126:
>
> Interfaces to Semantic Systems
>
> All computer systems, including legacy systems, are becoming
> semantic systems that directly or indirectly access the WWW.
>
> Different people require different interfaces:
>
> * Casual users – anybody who opens an unfamiliar application.
>
> * Subject matter experts who are updating a knowledge base.
>
> * IT professionals who must address the internal representations.
>
> The terminology of a subject is the key to interoperability:
>
> * SMEs are the people who know the subject matter.
>
> * Their terminology is the basis for all communications about
> the subject among people and computer systems.
>
> * Their primary interface must be a CNL that is automatically
> translated to and from any internal knowledge representations.
>
> * The technology for doing those translations was a research
> topic thirty years ago, but it has been deployed in many
> practical systems today.

> Conclusions
>
> The logicians Peirce, Whitehead, and Wittgenstein
>
> * Had the highest regard for the precision of logic and
> mathematics,
>
> * Observed that the starting assumptions for logic and ontology
> are based on prelogical insights expressed in ordinary language.
>
> Semantic systems are based on the semantics of communication
>
> * Among people in ordinary language,
>
> * Between people and computers in ordinary language,
>
> * Among computers in categories expressible in ordinary language.
>
> Technology available today can
>
> * Translate controlled NLs to and from computable notations,
>
> * Find and extract significant patterns from unrestricted NLs.
>
> Methodologies for developing and using semantic systems should
> take advantage of technology for NLs, controlled and unrestricted.
